A lid 10 of this disclosure further comprises a manual fluid pump operationally configured to direct fluid out from the fluid additive reservoir 15 of the lid 10 to a target destination or target location external the lid 10, e.g., direct fluid out from the fluid additive reservoir 15 into a fluid reservoir of a corresponding beverage container 5 or to another location external the lid 10 such as a sink, a waste basket, a liquid container, a mouth of a person or animal, a floor or ground surface, or other target destination as desired. With particular reference to the embodiments of FIGS. 1-5, one suitable manual fluid pump includes a primer bulb pump or “primer pump 25” attached to the exterior part 13 of the housing 12 and operationally configured to direct fluid out from the fluid additive reservoir 15 to a target destination such as into a fluid reservoir 6 of a corresponding beverage container 5. Referring to FIGS. 4 and 5, in one embodiment the primer pump 25 includes (1) a mounting body 26 operationally configured to sealably mate with an opening of the housing 12, (2) a flexible or depressible hollow bulb 27 connected to the mounting body 26 and located external the housing 12, (3) at least one upstream fluid conduit 28 having a proximal end connected to the mounting body 26 in fluid communication with the bulb 27 and a distal end 30 in fluid communication with the fluid additive reservoir 15 and (4) at least one downstream fluid conduit 29 having a proximal end connected to the mounting body 26 in fluid communication with the bulb 27 and a distal end 31 located external the fluid additive reservoir 15 and in fluid communication with the fluid reservoir 6 of a corresponding beverage container 5. As understood by persons of ordinary skill in the art of primer pumps, a hollow bulb 27 may be depressed one or more times to expel air out from the bulb 27 through the downstream fluid conduit 29 wherein the negative pressure within the bulb 27 is effective to draw fluid additive 100 from the fluid additive reservoir 15 through the upstream fluid conduit 28 away from the interior part 14 of the housing 12 and the fluid reservoir 6 (see directional Arrow A) into the bulb 27 as shown in FIG. 5. As fluid additive 100 enters the bulb 27, additional depressing of the bulb 27 is effective to expel air and fluid additive 100 out from the bulb 27 through the downstream fluid conduit 29 into a fluid reservoir 6 of a corresponding beverage container 5 (see directional Arrow B) wherein the fluid additive 100 may mix with liquid such as a beverage 7 stored within the fluid reservoir 6. As also understood by persons of ordinary skill in the art of primer pumps, a bulb 27 as described herein may also serve as a fluid reservoir for fluid received from the fluid additive reservoir 15. In addition, although the directional Arrows A and B illustrate up-and-down vertical flow of fluid additive 100 according to the vertical orientation of the upstream fluid conduit 28 and the downstream fluid conduit 29, in another embodiment, the upstream fluid conduit 28 and/or the downstream fluid conduit 29 may comprise a non-vertical orientation.

For purposes of operation with a beverage container 5 of this disclosure, one suitable bulb 27 may include an outer diameter of or about 1.5 cm (0.59 inches) and include an apex at a distance of or about 2.0 cm (0.79 inches) from the mounting body 26 of the primer pump 25, i.e., an apex at a distance of or about 2.0 cm (0.79 inches) from the exterior part 13 of the housing 12. One suitable bulb 27 may be constructed of one or more transparent flexible plastics. In another embodiment, a bulb 27 may be constructed of one or more non-transparent flexible plastics. In another embodiment, a bulb 27 may be constructed of one or more semi-transparent flexible plastics. One non-limiting example of a primer pump 25 of this disclosure as depicted in FIG. 6 includes a snap-in primer assembly commercially available from Walbro, Tuscon, Ariz., U.S.A. As understood by the skilled artisan, commercially available primer assemblies typically comprise replaceable bulbs 27. As also understood by the skilled artisan, a primer pump 25 of this disclosure may be operationally configured for use with liquids within a certain viscosity range. For use as part of a lid 10 for a beverage container 5, in one embodiment a primer pump 25 is operationally configured for use with liquids having a dynamic viscosity the same or similar as water at temperatures above 0.0° C. (above 32.0° F.). As understood by the skilled artisan, the dynamic viscosity of water at 1.0° C. (33.8° F.) is 1.7323 cP, the dynamic viscosity of water at 20.0° C. (68.0° F.) is 1.0005 cP and the dynamic viscosity of water at 96.1° C. (205.0° F.) is 0.293 cP.

As shown in FIG. 5, fluid additive 100 may be directed from a first location (or “first fluid location”) within the fluid additive reservoir 15 of the housing 12 to a second location (or “second fluid location”) external the housing 12, i.e., external the exterior part 13 of the housing 12 within the bulb 27 of the primer pump 25 before being conveyed to a third location (or “third fluid location”) external the housing 12 within a fluid reservoir 6 of a corresponding beverage container 5. Accordingly, a primer pump 25 of this disclosure provides a multi-directional fluid pathway for fluid additive 100 from an initial fluid location within the fluid additive reservoir 15 through the bulb 27 to a final location external the downstream fluid conduit 29. In one embodiment, a primer pump 25 may be constructed to include an upstream fluid conduit 28 and a downstream fluid conduit 29 of a desired length, inner diameter, outer diameter and shape or configuration. As further shown in FIG. 5, in one embodiment the proximal end of the upstream fluid conduit 28 may be connected to the mounting body 26 at a higher elevation than the proximal end of the downstream fluid conduit 29 whereby fluid additive 100 within the bulb 27 may flow toward the downstream fluid conduit 29 via gravitational flow.

In one embodiment of a primer pump 25 as shown in FIG. 6, the upstream fluid conduit 28 and the downstream fluid conduit 29 may be provided as tubular members or other conduits, each being defined by a longitudinal axis. In another embodiment, the upstream fluid conduit 28 and/or the downstream fluid conduit 29 may be provided as non-linear tubular members or other conduits comprising one or more turns or bends thereby providing non-linear fluid flow there through. In another embodiment, a primer pump 25 may include one or more add-on tubular members or other conduits fluidly communicated with the upstream fluid conduit 28 and/or the downstream fluid conduit 29 of the primer pump 25 in a manner effective to extend the operable length of the upstream fluid conduit 28 and/or the downstream fluid conduit 29. Non-limiting examples of add-on tubular members may include, but are not necessarily limited to fixed shape tubing, flexible tubing, and combinations thereof that may be adhered to and/or mechanically connected to the upstream fluid conduit 28 and/or the downstream fluid conduit 29 of a primer pump 25 and also adhered to and/or mechanically connected to other add-on tubular members and/or other conduits. As such, the upstream fluid conduit 28 and/or the downstream fluid conduit 29 are not limited to any one shape or configuration, but may include a shape or configuration best suited for flowability of one or more particular fluid additives 100 and/or a shape or configuration operable with a lid 10 of a particular construction including particular structural features, e.g., a particular housing 12 size and/or shape configuration, a particular fluid additive reservoir 15 size and/or shape configuration, the location of a primer pump 25 along a housing 12, the configuration of the interior part 14 of the housing 12, and combinations thereof.

With further reference to FIG. 5, a distal end 30 of the upstream fluid conduit 28 may terminate at or near the interior part 14 of the housing 12 effective for the primer pump 25 to transfer substantially all or most of the fluid additive 100 out from the fluid additive reservoir 15. In one non-limiting embodiment, a distal end 30 of the upstream fluid conduit 28 may terminate at a distance of or about 0.5 mm (0.0197 inches) from the inner surface of the interior part 14 of the housing 12 up to or about 5.0 mm (0.197 inches) from the inner surface of the interior part 14 of the housing 12. Although the interior part 14 of the housing 12 is depicted in FIGS. 1-5 as comprising a planar horizontal type inner surface, in another embodiment the inner surface of the interior part 14 of the housing 12 may comprise a non-horizontal type surface, for example, a sloped surface operationally configured to direct fluid additive 100 via gravitational flow toward the open distal end 30 of the upstream fluid conduit 28 as shown in FIG. 7. As depicted in FIG.

5, in one embodiment the downstream fluid conduit 29 may include a length whereby an open distal end 31 of the downstream fluid conduit 29 is located within a fluid reservoir 6 of a corresponding beverage container 5 during operation of the lid 10. In another embodiment, the distal end 31 of the downstream fluid conduit 29 may terminate at the interior part 14 of the housing 12 similar as the fluid inlet 24 of the fluid conduit 21 as shown in FIG. 4. Although the lid 10 may be built to scale, a lid 10 as shown in FIGS. 1-5 operationally configured for use with a portable hand held type beverage container 5 may include an upstream fluid conduit 28 and a downstream fluid conduit 29 with lengths as described in Table 1.
